Python For Loop Example to Iterate over a Sequence

Python For Loop Example to Iterate over a Sequence. The enumerate() function takes an iterable and returns an enumerate object (an iterator) that produces a tuple of the form (index, value), where index refers to the offset of the item and item refers to the corresponding item from the iterable., In Python, Set is an unordered collection of data type that is iterable, mutable and has no duplicate elements. There are numerous ways that can be used to iterate over a Set. Some of these ways provide faster time execution as compared to others. Some of these ways include, iterating using for.
